Challenge

Industry Loss Warranty Trigger Verifier using LangChain and LangGraph

Industry Loss Warranties depend on reliable, tamper-evident verification of physical and monetary catastrophe loss thresholds. You will build a stateful verification pipeline using LangChain and LangGraph to correlate multi-source weather sensor feeds with index loss reporting. Achieve zero false-positive trigger executions and sub-second validation latency across catastrophe scenarios.

Evaluation rubric

How submissions are scored

These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

zero_false_positives

No contract triggering when actual industry loss is below threshold.

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

validation_latency_ms

Time taken to complete graph evaluation in milliseconds • target: 500 • range: 0-1000

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
